Phylogenetic analysis of putative β-type carbonic anhydrases (CAs) from P. tricornutum. A neighbor-joining tree is shown of putative or described β-type CAs from several lineages within the eukarya and eubacteria, including the two P. tricornutum β-type CA-like NRS sequences (in bold). The sequences were selected to represent 5 out of the 6 major clades of β-type CAs that contain photosynthetic or eukaryotic orthologs (A, B, C, monocots, and dicots; Smith et al., 1999) and trimmed to a conserved core of 191 amino acids. The Mycobacterium tuberculosis sequence, a distant ortholog of the sixth clade D, was chosen to root the tree. Bootstrap values above 70% (of 1,000 replicates) are shown. The GenBank GI sequence identifiers of the proteins used are shown following the species name. Members of the Rhodophyta (Rp), Cyanobacteria (Cb), and Viridiplantae (Vp) are indicated. Scale bar = 0.1 substitutions/site.
